A study of the cyclodextrin complexes of flavonoids by thin layer chromatography

The complexation of various flavonoids with cyclodextrins and cyclodextrin derivatives was studied using thin layer chromatography on cellulose. The results indicate that the flavonoids examined do not complex readily with α-cyclodextrin or with succinylated α-cyclodextrin. However, most do complex with β-cyclodextrin, succinylated β-cyclodextrin, succinylated γ-cyclodextrin, α-cyclodextrin polymer, β-cyclodextrin polymer and γ-cyclodextrin polymer. With γ-cyclodextrin elongated trails are obtained, suggesting that the kinetics are somewhat slower. © 1997 John Wiley & Sons, Ltd.
